When CONFIG_IOMMU_API isn't set the following warnings pops up:
drivers/gpu/drm/tegra/vic.c: In function ‘vic_boot’:
drivers/gpu/drm/tegra/vic.c:110:31: error: implicit declaration of function
‘dev_iommu_fwspec_get’; did you mean ‘iommu_fwspec_free’?
[-Werror=implicit-function-declaration]
struct iommu_fwspec *spec = dev_iommu_fwspec_get(vic->dev);
^~~~~~~~~~~~~~~~~~~~
iommu_fwspec_free
drivers/gpu/drm/tegra/vic.c:110:31: warning: initialization of ‘struct
iommu_fwspec *’ from ‘int’ makes pointer from integer without a cast
[-Wint-conversion]
drivers/gpu/drm/tegra/vic.c:117:19: error: ‘struct iommu_fwspec’ has no member
named ‘num_ids’
if (spec && spec->num_ids > 0) {
^~
drivers/gpu/drm/tegra/vic.c:118:16: error: ‘struct iommu_fwspec’ has no member
named ‘ids’
value = spec->ids[0] & 0xffff;
^~
Rework so that its inside a '#ifdef CONFIG_IOMMU_API' block.
